Abstract: An intervertebral spinal implant includes a shaped body with a first bearing side, a second bearing side located opposite to the first bearing side, a front part, a rear part, a concave side and a convex side. The concave side and the convex side are both connected to the bearing sides as well as to the front part and the rear part. The first bearing side and the second bearing side are each provided with at least two projections for penetration within a vertebral body's wall. The projections are formed by elongated sliding-guiding runners which extend in a diverging manner from the concave side of the body towards the convex side of the body. The sliding-guiding runners extend in a curved manner so that they also extend from the concave side of the body towards the rear part of the body in addition to extending towards the convex side of the body. The sliding-guiding runners are provided with a smooth surface facing the convex side of the body and with a rough surface facing the concave side of the body.
